IMPROVED CISTERN FOR DRAINING PEAT.

Specification forming part of Letters Patent No. 53,769, dated April l0, 1866.

To all whom it may concern:

Beit known that I, E. H. ASHCROFT, of the city et' Lynn, county of Essex, in the State of Massachusetts, have invented a new and 1mproved Tank for Draining Peat Preparatory to its Use for Fuel; and I do hereby declare that the tbllowing is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the peculiar construction ot' a tank or vessel, insuring much more rapid drainage, effected by the additional use ot' perforated tubes passing up from the bottom ot' the vessel to or near its top. l

It is well known to all skilled in the art that in the prepa-ration of peat for fuel it has to undergo several processes by machinery, &c.,

one condition ot' its usefulness being certain dryness. Goed drainage promotes this and facilitates the manufacture.

T6 enable others to make and use my invention, I will proceed to describe it.

In the drawings, Figure 1 represents a perspective view et' my draining-vessel, showing its sides and bot-tom well perforated. The exterior shape of the vessel may vary in formfor instance, may be cylindrical, &c. Fig. 2 shows a transverse section of Fig. 1.

A indicates the sides and bottom; a, the perforatiens'in the same; B, tubes, also perforated, as shown at b, which are secured to the bottom ot the vessel and opening through it'. The number of these/pertbrated tubes can be regulated by the size of the vessel. By the use of them the draining-surface is greatly intherewith. i E. 1I. ASHGROFT. Witnesses:
